Chapter 11.8, Problem 18CC

Interpretation Introduction

Interpretation:

The propagation steps involved for the given reaction conditions should be determined.

Concept introduction:

Ozone depletion:

Ozone serves as a protective layer which prevents the harmful ultraviolet rays. The ozone layer is situated in the upper atmosphere. The hazardous substances especially like chlorine reacts with the oxygen atoms in ozone that results in the depletion of the ozone layer.

The propagation steps involved in depletion of ozone layer,

Propagation: In this stage, two steps are involving halogen abstraction (no change in the number of free radicals)
